分式加减计算9a^2/(3a-2b)+4b^2/(2b-3a)分式加减计算9a^2/(3a-2b)+4b^2/(2b-3a)分式加减计算9a^2/(3a-2b)+4b^2/(2b-3a)=9a

分式加减计算9a^2/(3a-2b)+4b^2/(2b-3a)
分式加减计算9a^2/(3a-2b)+4b^2/(2b-3a)

分式加减计算9a^2/(3a-2b)+4b^2/(2b-3a)
=9a²/(3a-2b)-4b²/(3a-2b)
=(9a²-4b²)/(3a-2b)
=(3a+2b)(3a-2b)/(3a-2b)
=3a+2b

原式=9a^2/(3a-2b)-4b^2/(3a-2b)=(9a^2-4b^2)/(3a-2b)=(3a 2b)(3a-2b)
